BOOKBINDER Frank Amato, New York, N. Y., assignor to Kamket Corporation, New York, N. Y., a corporation of New York Application December 21, 1935, Serial No. 55,556 4 Claims. (01. 129-23) This invention relates to book binders and more I on both sides of the fastening means 5, thereby particularly to that class of book binders in which providinga line of flection of the portion 6. along an outer folder or cover is provided with means the line of rivets 5 and support forv the structure for accommodating and holding loose sheets by thatportion of the support 4 lyingopposite 5' which are attachable or detachable yat will, from the flexible portion 6. The binder element 1 is l5 i the cover and the binding means. i preferably made of wire or other stock material,

The main object of this invention is to provide which is bent into a plurality of sheet-retaining an inexpensive book binder. the folder or cover members 8, preferably of ring .conformation, iOf which can be packed 'and shipped flat, apart tongues 9, and tie members "1. In forming the .l0' from the binding element, and in which the bindbinder element 1 of stock material such as wire, 0

The binder element in association with ticular number of rings required for the size of the folder or cover, is manipulata-ble by a swingthe book binder. In the course of formation of 15 ing orrolling motion, to a position for inserting the binding element, each sheet-retaining memsheets therein and adapted to be placed in a poher or ring 8 is made up of a double thickness of sition in'which the sheets under ordinary mawire, or other stock material, and the tongues 9 nipulation, as in a book, will not be displaced. are likewise made of double thicknessof stock y To utilize the binder of this invention it is not material, while the tie members Ill are made of necessary to have anyspecial tools for. opening si gle thickness stock material. An examinathe binder, or catchesto lock the sheets in the tion of Fig. 2 shows the course of the stock mabinding element. Other advantages of this interial as it is bent into configuration, the first vention will appear from the following descripconvolution ll terminating in one leg l2 of the 5 tion.

The second convolution l5 termithe same position as in Fig. 2, and Fig. 4 is a mates in the tie member [8 which unites adjoincross section of the book binder with the folder ing convolutions. of the series of sheet-retaining or cover closed. i members. In the course of construction ofthe The cover or folder 1 preferably comprises two binding element 1, the tongues 9 do not partake members 2 and 3, member 2 forming the topcover of the curvature of the rings 8 and do not engage 40 of the folder or cover, and membefiii forming the the ends of the rings associated with the tie membottom cover. It is preferred to utilize both a top bers I0, but are spaced therefrom to provide open- ..and bottom cover, but the top cover may be disings IT. The tongues 9 are relatively short and pensed with if it is not desirous of covering the extend ashort distancebeyond the plane in which sheets comprising the book. Th'ebottom cover 3 the inner edges of the rings 8 .lie, thereby defin- 45 is provided with a support 4 preferably made of mg the openings IT, on the underside, by the fairly stiff, but flexible, cardboard -,or other sheet tongue 9, the rings 8 and the bend in the tie material. The support 4 is secured to the botmember II] where it joins, at I6, aconvolution of tom cover by suitable fastening means, for inone of the rings 8. The support 4 is provided so stancehollow rivets 5, positioned inside of the with a plurality of perforations l8 equal innum outside edge of the support 4, thereby providing ber to the number of tongues and ring members a fleir'ible portion 6 which is part of the support 4 constituting the binding element. These perfoand which flexible section lies between the outer rations. I8 are formed just inside of the free edge I edge of-the support 4 and a line drawn through of the portion 6, in order that the distance from the rivets 5. It is preferred to extend the support such free edge to the perforations is not greater 55 UNITED STATES PATENT OFFICE than the openings I! in the rings 8, to permit free passage of the edge of the flexible portion 5 through such openings IT. The binding element is positioned with respect to the folder and the support 4 by inserting the tongues through the perforations l8, as shown in Fig. 2, and then turning the entire binder element about its central axis and tucking tongues 9 beneath portion 6 so that the binder element assumes the posi-- tion shown in Fig. 1. The support 4 provides a stiffening means for the bottom cover 3, but the flexible portion 6 is capable of movement by flection toward and away from the inside face of the bottom cover 3. The length of the tongues 9 is less than the distance from the outer edge of the flexible portion 6 to line in which the fastening means or rivets 5 lie. That portion of the folder which will constitute the back of the book is preferably scored with a series of parallel lines I9 in order to provide a back for the book and permit such back to follow the general contour of the ring members 8.

The binder element is assembled in the cover in association with the support 4 by inserting the ends of the tongues 9, from the underside of the flexible portion 6, into the perforations H3 in the support 4. The entire binding element is then pushed upwardly so that the tongues slide completely through the perforations I8 and the free I edge of the flexible portion 6 slides through the openings l1 into engagement with the rings 8, as illustrated on an enlarged scale in Fig. 3. The tongues are then pushed toward the left, which causes rotation of the entire binder element 1. Continued rotation of the binder element through the perforations l8, causes engagement of the ends l3 of the tongues 9 with the inside of the top cover, the tongues riding over the inside of the cover and lifting the free end of the flexible portion 6 (shown in Fig. 4) from the bottom cover 3 and the insertion of the tongues into the space formed between the bottom cover 3 and the underside of the flexible portion 6. The final relation of the parts is shown in Fig. 1, in which the tongues are tucked beneath the flexible portion 6 and the underside of the flexible portion 6 engaging the tie members Hi. When it is desirous to insert a sheet in the folder, the top cover 2 is thrown to the left and some of the ring members 8 are grasped and rolled toward the right. This action causes the support 4 to flex and the ends l3 of the tongues 9 to ride over scorings I9 and -continued rolling of the binder element 1 will ultimately bring the tongues into the position shown in Fig. 2, in which they stand substantially upright. This motion brings the openings H from the covered position shown in Fig. 1, to the exposed position shown in Fig. 2. The ends l3 of the tongues are inserted through the perforations 20 in the sheets which are to be added to the book, until the sheets lie approximately in the position shown in Fig. 3, having passed through the openings I l in the binder element. The binder element is now rotated or rolled toward the left, the edges l3 thereof riding over the scorings l9 while the flexible portion 6 flexes upwardly. Continued rotation or rolling of the element causes the tongues to again pass beneath the flexible portion 6, thereby covering the openings l1 beneath the flexible portion 6, as shown in Figs. 1 and 4. The entire weight or burden of the sheets carried by the support 4 and the-folder l engaging its top and bottom covers 2 and 3, merely provide covers for the sheets and the binding element.

The entire folder is preferably made so as to be flexible throughout, reinforced, and slightly stiffened only by the support 4 which extends substantially lengthwise of the lower cover with its outer edge close to that portion of the folder which forms the back of the book. The tongues 9 are extremely short in order that said tongues will properly function with the other elements of the invention. The length of the tongues is limited to extend just beyond the vertical plane in which the openings 11 and the tie bars I0 lie as seen in Fig. 4. Tongues of such character, when the book is completed, extend just beneath the free edge of the support 4, permitting the manipulation of the sheets of the book in the normal manner without the escape of the sheets from engagement with the ring-like members, but nevertheless permitting the tongues to be rotated or swung to open position for the ready insertion of sheets over the exposed tongues and through the ring openings.
